Ma King-sang

"So I'm a flunkey. A flunkey with money is as good as a king. And you? A poor teacher, so pure. You have to repair umbrellas to eat. Does that feel good? You can't eat purity, can you? Ask yourself which of your students still remember you? Which still cares about you? All of them, they're with me now."

- Ma taunting his former master.

Ma King-sang (馬鯨笙) was the leader of the Hong Kong Triad and a former student of Tin Ngo-san.

Ma used to practice Wing-chun under Tin Ngo-san until he quit for an unspecified amount of time. During his absence, he used whatever martial arts skills that he had for illegal activities and eventually became the leader of the Hong Kong Triad, a criminal group that was employed by Frank to act as enforcers to acquire the land occupied by a school through illicit means. After an intense confrontation with Ip Man and Ngo-san, he ended up being humiliated by the latter two and hired Cheung Tin-chi to get revenge on his former master. However, after he kidnaps Ip and Tin-chi's sons, along with other children, and threatens to sell them to slavery in a last attempt to try to take over the school, Ip and Tin-chi manage to defeat his entire gang, which resulted in the arrest of all Triad members, except for Ma. Despite managing to escape, he is eventually fired by Frank for his numerous failed attempts to acquire the school.

He is the secondary antagonist of the 2015 film Ip Man 3.

Ip Man 3
Ma first appears watching his acquaintance Cheung Tin-chi participating in underground fights to earn extra money, to which he regularly comes out successful in the end. It soon turns out that Ma is working for his benefactor named Ip Man, an American property developer and proficient boxer.

Frank orders Ma to acquire a piece of land occupied by the school where Ip Ching and Cheung Fung study. Ma asks for a month for it to be done, but is threatened into assuring that it will be done within two weeks.

The next day, when Ip goes to pick up his son from school, he witnesses Ma and his men coercing and beating the headmaster, who refuses to sell them the school. Ip interferes and restrains Ma, but is forced to let him go. Ip seeks help from his close friend "Fat Po", a local police detective. Fat Po agrees to help Ip, but claims a shortage of manpower and influence. Ip then decides to guard the school alongside his students.

That night, they fend off an attack by Ma's men, who attempt to set fire to the school and kidnap the headmaster. Cheung, who happened to be passing by, helps fight off the invaders and rescues the headmaster. Cheung's skills impress Ip, and he thanks Cheung for his help. Tin Ngo-san, a local martial arts master and Ma's former mentor, is enraged by Ma's unscrupulous acts, and accompanied by Ip, confronts Ma at the Hong Kong shipyard where he humiliates him in front of his men. Ma retaliates with a hidden knife, but Ip is able to stop him. Fat Po arrives and keeps the situation at bay, but Ip eventually lets Ma go again to de-escalate the situation. Ma finds Cheung and offers him a large sum of money to get revenge against Tin on his behalf. Desperate to open his own martial arts school, Cheung accepts the offer and is able to put Tin in the hospital. Ip receives a call from the hospital and visits Tin.

Upon learning that Tin did not call him, Ip realizes it was a set-up by Ma to lure him away from the school, so that his gang could kidnap some of the students, including Ip Ching and Cheung Fung. Ip arrives alone at Ma's shipyard, where Ma holds Ip Ching at knife point and threatens to sell the children into slavery if the headmaster refuses to surrender the school. Upon learning that his son was also kidnapped, Cheung arrives and is allowed to leave with his son due to being an associate; but after his son tells him that they still have his friends, he returns and fights alongside Ip. Ip and Cheung are able to hold their own until a troop of policemen led by Fat Po comes to arrest the gang, while Ma flees. After the incident, Frank dismisses Ma and sends his assassin called the Muay Thai Warrior to go after Ip instead.
